STOCK Application filed April 10,

Our invention relates to a stock oiler of the type disclosed in our issued Patent No. 1,566,558, issued December 22, 1925, and it is our object to improve upon the construction of such an oiler by simplifying such structure.

More specifically, it is our object to provide an oiler comprising a gate. adapted to be mounted in a fence or the like, means for spraying oil from above said gate, and means for directing the spray of oil to the side of the gate away from the direction in which the gate swings, such shifting of the spray being accomplished in the present invention by the use of a single nozzle, the position of which is changed by the swinging of the gate.

WVith these and other objects in view, our invention consists in the construction, arrangement and combination of the various parts of our device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims and illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation of the oiler.

Fig. 2 is an end elevation of the same.

Fig. 3 is a plan view of the same.

Fig. 1 is a detail sectional view, taken on the line 1 1 of Fig. 1.

Fig. 5 is a detail sectional view, taken on the line 5-5 of Fig. 2, and

Fig. 6 is a detail sectional view, taken on the line 6-6 of Fig. 1.

Although we have shown in the aocom panying drawings an integral structure embodying a gateway and a gate, it will be understood that the invention may be prepared in the form of a gate adapted to be mounted in any sort of gateway which may be provided.

The gateway is shown generally at 10, and has the side uprights, 11 and 12, and the upper cross piece, 13. To the upright, 11, is secured a bracket, 14:, having a hearing, 15, which, together with the bearing 16, secured to the upright, 12 journals a shaft, 17. The gate, 18, which may be of sheet metal or any other construction is hung from the shaft, 17, and secured thereto as by the loops, 19. It will thus be seen that swinging of the gate will cause the shaft, 17, to oscillate.

The bracket, 14:, has a socket, 20, which receives the pump cylinder, 21. A cap, 22, bolted to the socket, 20, secures the cyliin HARRISON, OF SIOUX CITY, IOWA.

der, 21, in place. The cylinder, 21, is fed with oil from a tank, 22*, which has been shown in Fig. 1 and omit-ted from the rest of the figures.

Thepiston of the pump, which is not shown, is actuated by the piston rod, 23, extending through a packing gland, 24, in the lower end of the pump. A crank arm, 25, is secured in the end of the shaft, 17, and has a bifurcated portion, 26, receiving the end of a pitman, 27, which is linked pivotally thereto and to the rod, 23, as shown.

The oil is delivered from the pump cyl inder, 21, through a goose neck, 28 which extends around the shaft, 17, to a pipe, 28. The pipe, 28, has a vertical portion, 29, provided at its lower end with a flange, 30. A packing nut, 31, engages the flange, 30, against the end of the goose neck, 28 and a packing ring, 33, is interposed to prevent leakage of the oil. This construction allows the pipe, 28, to swing laterally.

A check valve, 32, prevents flow of oil back into the tank, 22, and a check valve, 32*, prevents flow of oil rearwardly from the pipe, 28, to the pump cylinder.

The other end of the pipe, 28, as at 34-, forms a nozzle which extends downwardly through a transverse slot, 35, in the top cross piece,.13, of the gateway. The nozzle may swing laterally of the gateway within the slot, 35. A nut, 36, supports the free end of the pipe, 28, and slidingly bears against the upper surface of the cross member, 13.

Any sort of flexibleconnection may be employed as a substitute for the construction shown in Fig. 5, and the nozzle instead of swinging bodily laterally may be allowed, for instance, to tilt laterally around a horizontal instead of a vertical axis, and yet accomplish the same result, namely, directing the oildischarge from the nozzle to one side or the other of the gate.

In order to control the swing of the nozzle in either manner above mentioned, we provide a lever co-acting with the lower end of the nozzle and actuated to swing the lower end to one side or the other of the gate. The lever is shown at 3'7 and is pivoted to the under side of the cross piece at The free end of the lever has an opening, not shown, which loosely receives the nozzle, 34.

Intermediate the ends of the lever is a depression, 39, which receives a stud, 1O, secured in the shaft, 17, and projecting upwardly. (See Fig 6.) The lever is provided with a ring, 41., surrounding the depression, 39, so as to prevent disenga gemeut oi the stud, 40, from the lever.

It will now be seen that as the gate is swung in one direction the stud, 40, will move in the other direction and carry the lever with it. The lever, swinging around a vertical axis in a direction reverse to that of the swing of the gate will move the nozzle to one side or the other of the gate.

The action of the stud, 40, in moving the lever, 37, is very rapid and takes place during the commencement of the swing of the gate. On the other hand, the action of the pum increases as the gate is swung outwar ly, and at the beginning of the swing there is no pump action whatever. This is due to the crank arm operating means, the arm, 25, being on dead center with the pitman, 27, when the gate is depending in its normal vertical position. (See Fig. 3.) As the angle of the arm, 25, changes during its swing the relative movement oi the piston rod, 23, will be increased.

The parts are'so arranged that the gate will have swung sufficiently to move the nozzle, 34., to either of its extreme positions where the stream of oil will not be interfered with by the shaft, 17, before the nozzle begins to eject the oil. The slight play in the pivotal connection between the arm, 25, the pintle, 27, and the piston rod, 23, aids in accomplishing this result.

The length of the lever, 37, beyond the depression, 39, is suflicient to magnify the movement imparted to the lever by the stud, 40, several times, and consequently the engagement of the stud, 40, with the depression, 38, need occupy only a small portion of the swing thereof. As the stud moves to one side it will slip out of the depression and slide within the ring, 41, which prevents binding of the stud against the lever as it swings back to reenter the depression, 38.

Some changes may be made. in the construction and arrangement of the parts of our invention withoutdeparting from the real spirit and purpose of our invention, and it is our intention to cover by our claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope lVe claim as our invention:
